Description

Technical Field

[0001] This utility model relates to the field of folding chair technology for courtyards, specifically to an outdoor folding chair with a seat and footrest. Background Technology

[0002] Outdoor courtyards refer to open outdoor areas, which are different from indoor areas. Outdoor activities are activities in open-air places. Folding chairs are lightweight and stackable seats that are easy to move and save space, adapting to various usage situations. With people paying more and more attention to outdoor leisure and entertainment, the overall market demand is constantly growing. They are widely used for home use, camping, beach outdoor leisure, sports events and gatherings, etc. Outdoor courtyard folding chairs can provide leisure spaces.

[0003] In the prior art, outdoor patio folding chairs require multiple bolts to be used for adjustment and locking. Since the device is set outdoors, the bolt connections are prone to rust and corrosion, making it difficult to adjust the position of the outdoor patio folding chair during long-term use. Therefore, this device provides an outdoor patio folding chair with a seat footrest. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of the existing technology by providing an outdoor courtyard folding chair with a seat and footrest, thereby solving the aforementioned technical problems.

[0005] The present invention adopts the following technical solution: an outdoor courtyard folding chair with a seat and footrest, including a folding chair support frame, a hollow weight reduction hole is provided on one side of the folding chair support frame, a movable shaft and an auxiliary shaft are rotatably installed on the inner side of the folding chair support frame, and folding chair operation control components are provided on the folding chair support frame and the movable shaft.

[0006] The folding chair operation control assembly includes a drive shaft, bevel gears, a slide rod, and a control knob. The drive shaft is rotatably mounted on the upper and lower inner sides of the folding chair support frame. The bevel gears are respectively fixedly mounted on the outer sides of the drive shaft, the movable shaft, and the auxiliary shaft. The slide rod is slidably mounted on the inner side of the drive shaft. The control knob is fixedly mounted on the front side of the slide rod, and the slide rod is slidably mounted on the inner side of the folding chair support frame.

[0007] Preferably, a seat cushion body is fixedly installed between opposite sides of the folding chair support frame, and a folding chair control locking component is provided on the outer side of the folding chair support frame and the auxiliary shaft.

[0008] Preferably, the folding chair operation control assembly further includes a lumbar support, a headrest, a protective cushion, and ventilation holes. The lumbar support is fixedly installed on the outside of the movable shaft, the headrest is fixedly installed on the front side of the lumbar support, the protective cushion is fixedly installed on the lumbar support, and the ventilation holes are formed on the lumbar support and the protective cushion.

[0009] Preferably, the folding chair control locking assembly includes a rotating foot pedal, a fixed cylinder, a limiting groove, a rotating seat, and a spring. The rotating foot pedal is fixedly installed on the outside of the auxiliary shaft, the fixed cylinder is fixedly installed on the rear inner wall of the folding chair support frame, the limiting groove is opened on the front side of the fixed cylinder, the rotating seat is rotatably installed on the rear inner wall of the limiting groove, and the spring is fixedly installed on the front side of the rotating seat.

[0010] Preferably, the folding chair control locking assembly further includes a locking block and a meshing tooth. The locking block is fixedly installed on the front side of the spring, and the meshing tooth is fixedly installed on the outside of the locking block. The meshing tooth engages with the limiting groove.

[0011] Preferably, the front side of the folding chair support frame has two sliding grooves, and the two sliding rods are slidably installed inside the corresponding sliding grooves.

[0012] Preferably, the front side of the drive shaft has a cross groove, the slide rod is cross-shaped, and the slide rod is slidably installed inside the cross groove.

[0013] The above-mentioned technical solutions adopted in the embodiments of this utility model can achieve the following beneficial effects:

[0014] 1. The folding chair's operation control components transmit power through a cross-shaped connection between the drive shaft and the slide bar, coupled with the meshing transmission of bevel gears, to achieve angle adjustments for the lumbar support, headrest, and rotating footrest, all without the need for bolt connections. Compared to traditional bolt adjustment structures, this completely solves the adjustment difficulties caused by bolt rust and corrosion in outdoor environments. Even after long-term exposure to rain, snow, and humid environments, it maintains flexible operation. Turning the control knob drives the upper and lower drive shafts to rotate via the slide bar, which in turn drives the movable shaft and auxiliary shaft simultaneously via bevel gears, thus adjusting the lumbar support tilt angle and the height of the rotating footrest. This linkage design replaces the tedious operation of loosening and tightening bolts one by one, allowing a single person to complete the seating posture adaptation in seconds, greatly improving ease of use.

[0015] 2. In the folding chair's control and locking assembly, a spring pushes the locking block out, causing the meshing teeth to engage tightly with the limiting groove, automatically locking the adjusted position. To unlock, simply press the locking block to compress the spring and release the lock. This structure eliminates the need for manual bolt tightening, provides even locking force, and prevents loosening. It remains stable even during outdoor bumps or changes in load, avoiding the safety hazards caused by loose bolts in traditional chairs. The angles of the lumbar support and headrest can be infinitely adjusted via a control knob. Combined with protective padding and ventilation holes, it can accommodate the lumbar support needs of users of different heights. Rotating the footrest allows for height adjustment based on leg length, preventing leg numbness caused by prolonged sitting. Compared to traditional folding chairs with fixed angles, it effectively distributes body pressure and improves the comfort of outdoor rest. Attached Figure Description
